Answer:
Boundaries between the plates are of three types: divergent (i.e., moving ...

Read the excerpt from "The Monkey's Paw.”
"It had a spell put on it by an old fakir," said the sergeant-major, "a very holy man. He wanted to show that fate ruled people's lives, and that those who interfered with it did so to their sorrow. He put a spell on it so that three separate men could each have three wishes from it."
His manner was so impressive that his hearers were conscious that their light laughter jarred somewhat.
"Well, why don't you have three, sir?" said Herbert White, cleverly.
The soldier regarded him in the way that middle age is wont to regard presumptuous youth. "I have," he said, quietly, and his blotchy face whitened.
"And did you really have the three wishes granted?" asked Mrs. White.
"I did," said the sergeant-major, and his glass tapped against his strong teeth.
"And has anybody else wished?" persisted the old lady.
"The first man had his three wishes. Yes," was the reply; "I don't know what the first two were, but the third was for death. That's how I got the paw."
Which event does the excerpt foreshadow?
A. the sergeant-major's return to India and the resulting tragedy
B. the sergeant-major obtaining the paw and the resulting tragedy
C. Mr. White's refusal of the paw and the resulting tragedy
D. Mr. White accepting the paw and the resulting tragedy

A physics teacher performed a demonstration for a science class by pulling a crate across the floor and measuring the force with a spring scale. While she pulled, a student measured the acceleration of the crate with a handheld electronic device. The results of three trials are shown below. The teacher asked the class to calculate the acceleration of the crate based on the crate’s mass and the force she applied. What conclusion can be made about the difference between the CALCULATED acceleration and the ACTUAL acceleration that occurred in the trials?
Answer:

can a magnet attract a pure substance?
Answer:
Magnets strongly attract materials which already themselves have magnetic domains. They do not significantly attract many metals like gold, aluminum, silver, and even some types of high-chromium stainless-steel, which lack such domains. In fact, pure gold is slightly repelled.

Which is the best unit of measurement to investigate the weight of rabbits?
a: inches b: tons c: ounces d: feet
HELP DUE TODAY!
Answer:
It is ounces because it is asking for weight and you would not measure a rabbit by tons
Answer:
C. Ounces
Explanation:
C. Ounces because inches and feet measure height or length not weight, and tons is wayyyy to much. Tbh I think pounds would be the best unit but since it's not an option then ounces is the best choice. (srry if I confused you)

Earth's magnetic field is generated by the outer core. Which characteristics of this layer create that phenomenon? How do you think scientists pinpointed the cause of the magnetic field as the outer core?
Answer:
On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet.

1. Identify at least two tools scientists use to study stars and galaxies, then explain how the tools you chose assist scientists in their work.
2. Name at least three properties of stars revealed by spectral characteristics
3. In 3-5 sentences, explain how a star is formed.
Answer: 1.Spectroscopes breaks the light from a single material into its component colors the way a prism splits white light into a rainbow. It records this spectrum, which allows scientists to analyze the light and discover properties of the material interacting with it.
2.Optical Telescopes The now-indispensable optical telescope instrument was pioneered by Galileo Galilei in 1609, although others had created similar tools by then
2.A stellar spectrum can reveal many properties of stars, such as their chemical composition, temperature, density, mass, distance, luminosity, and relative motion using Doppler shift measurements.
3.Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the Sun.Once the pressure and the temperature inside get high enough for nuclear fusion to ignite, it creates a star.

Because of surface tension, a liquid _____.
resists flowing
forms a crystalline solid
takes the shape of its container
forms droplets
Because of surface tension, a liquid forms droplets. The surface tension makes the surface molecules experiences a strain from the bulk of the liquid.
What is surface tension ?Surface tension is the propensity for liquid surfaces that are at rest to condense into the smallest surface area. Razor blades and insects, which have a higher density than water, can float on the surface of the water without even becoming partially buried because to surface tension.
Force per unit length or energy per unit area are the dimensions of surface tension. The two are equivalent, although when discussing energy per unit of area, surface energy is frequently used because it is a more inclusive phrase that includes solids.
To minimize the surface area, liquids assume the shape of droplets. The uneven cohesive forces of the surface layer tend to pull water droplets into a spherical shape, even though they can be easily distorted. Hence, option d is correct.
